Scope
Scope: This document specifies the processing technical requirements, packaging, process quality control, and technical file management for buckwheat tea. This document is applicable to the production of buckwheat tea made from buckwheat as the raw material, through steaming, drying, dehusking, and roasting. Main technical content: Using buckwheat as the raw material, it is processed through steaming, drying, dehusking, and roasting. 4 Processing technical requirements Process flow: Buckwheat (raw material) - selection and removal of impurities - soaking - steaming - drying - dehusking - grading - roasting - color selection - sieving - packaging of buckwheat tea. Raw material quality requirements shall comply with GB 2715 and GB/T 10458. After removing impurities from the buckwheat raw material through screening, removal of impurities, removal of immature seeds, and magnetic separation, the total impurities shall be ≤0.2%.
